The invention relates to an electro-optical radiation protection device (1), in particular a light protection device, comprising at least one electro-optical protective sheet (1), which covers at least the visual field of one eye and comprises at least one liquid crystal element (2); at least two radiation sensors (3, 4, 5), each of which generates a control signal depending on the intensity of the incident radiation; and control electronics (6), which is designed to receive the control signals and to activate the or each liquid crystal cell (2), and which controls the degree of transmission (T) of the protective sheet (1) as a function of the control signals from the radiation sensors. The radiation sensors (3, 4, 5) are in the form of photodiodes having the highest sensitivity in the infrared range; the sensor surfaces (7, 8, 9) define sensor planes (SE3, SE4, SE5); at least two of the sensor planes (SE3, SE4) intersect one another at an angle of less than 45°; and the intersection line of these sensor planes (SE3, SE4) is preferably in, or parallel to, the sagittal plane (S) of the protective sheet (1).
